A mixing device for the production of a carp feed additive

Abstract

The present invention discloses a mixing device for the production of a carp feed additive, which relates to the technical field of additive production. A rotating tube is rotatably connected to a box body. The bottom end of the rotating tube is slidably sleeved with a sliding tube, and a plurality of fixed tubes are fixedly communicated with the sliding tube. Through the setting of the scraping and extrusion unit in the present invention, the motor drives the driving shaft to rotate. The rotation of the driving shaft drives the rotating tube, the sliding tube and the fixed tubes to rotate through two bevel gears, so that the rotating scraper can scrape the remaining materials adhered to the inner wall of the box body onto the material guiding plate. The rotation of the driving shaft drives the cam to rotate. When the cam presses the strip-shaped plate to drive the connecting rod and the sliding piston to move downward, the gas in the air storage cavity is squeezed into a plurality of fixed tubes through the rotating tube and the sliding tube, and then the gas pushes the sliding rod and the extrusion plate to move, so that the extrusion plate contacts the material guiding plate. Since the adhered remaining materials are easy to agglomerate, the agglomerated remaining materials can be broken, thereby improving the mixing effect of the materials.

Description

Technical Field

Specifically, it is a mixing and stirring device for producing feed additives, including a support ring and a sealing cover. A support block is arranged above the support ring, a positioning plate is arranged in the middle of the support column, an engagement ring is arranged in the middle of the positioning plate, a discharge port is arranged at the lower end of the main body housing, heating wires are arranged inside the heating layer, and fixing screws are installed at both the left and right ends of the sealing cover. This mixing and stirring device for producing feed additives relies on the rotation of the rotating shaft to drive the rotation of the sealing housing, the main shaft, and the auxiliary shaft, thereby realizing the stirring effect on the materials inside the main body housing.

[0017] The present invention provides a mixing device for producing carp feed additives through improvement. Compared with the prior art, it has the following improvements and advantages:

[0018] First: Through the setting of the scraping and pressing unit in the present invention, the motor drives the driving shaft to rotate. The rotation of the driving shaft drives the rotating pipe, the sliding pipe and the fixed pipe to rotate through two bevel gears, so that the rotating scraper can scrape the remaining materials adhered to the inner wall of the box body onto the guide plate. The rotation of the driving shaft drives the cam to rotate. When the cam presses the strip plate to drive the connecting rod and the sliding piston to move downward, the sliding piston moves downward to squeeze the gas in the air storage cavity into a plurality of fixed pipes through the rotating pipe and the sliding pipe, and then the gas pushes the sliding rod and the pressing plate to move, so that the pressing plate contacts the guide plate. Since the adhered remaining materials are easy to agglomerate, the agglomerated remaining materials can be broken, thereby improving the mixing effect of the materials.

[0019] Second: In the present invention, the movement of the pressing plate drives the installation block, the sleeve and the pressing column to move. The movement of the pressing column squeezes the spiral groove to drive the rotating shaft and the V-shaped plate to rotate. The rotation of the V-shaped plate can turn over the materials. The rotation of the rotating pipe drives the reciprocating sleeve to move back and forth through the spiral groove. The reciprocating movement of the reciprocating sleeve drives the fixed ring, the sliding pipe and the fixed pipe to move, so that the guide plate, the scraper and the V-shaped plate move, thereby improving the effects of turning over, scraping and stirring the materials.

[0020] Thirdly: With the arrangement of the scraping and extrusion unit in the present invention, the reciprocating movement of the shaft sleeve drives the movement of the extrusion rod. When the extrusion rod moves upward and contacts the inclined rod, the extrusion rod squeezes the inclined rod to drive the movable rod and the baffle to move outward. The movement of the movable rod drives the installation spring to stretch and undergo elastic deformation. The movement of the baffle opens the feed pipe, enabling the materials in the feed box to enter the discharging box through the feed pipe and then be discharged through the discharging port. When the extrusion rod moves downward and away from the inclined rod, the installation spring drives the baffle to reset and closes the feed pipe, thereby enabling intermittent feeding and making the materials mix more evenly. When the sliding piston moves downward, the gas in the air injection cavity can be squeezed through the one-way air outlet pipe into the jet head and sprayed out by the jet head. The sprayed gas blows the materials falling from the discharging port, thereby expanding the falling range of the materials and making the materials mix more evenly. Description of the Drawings

[0033] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] The present invention provides a mixing device for producing a carp feed additive through improvement. The technical solution of the present invention is as follows:

[0035] As Figures 1 to 9 shown, an embodiment of the present invention provides a mixing device for producing a carp feed additive, including a box body 1. A rotating pipe 11 is rotatably connected to the box body 1. The bottom end of the rotating pipe 11 is slidably sleeved with a sliding pipe 12. A plurality of fixed pipes 13 are fixedly communicated with the sliding pipe 12. It further includes;

[0036] A mixing mechanism, which is located on the box body 1;

[0037] The mixing mechanism includes a scraping and extrusion unit, a driving unit, and an intermittent discharging unit. The scraping and extrusion unit includes brackets 17 fixedly connected to one end of a plurality of fixed tubes 13 respectively. One end of each of the plurality of brackets 17 is fixedly connected with a material guiding plate 18. A scraping plate 19 is fixedly connected to the plurality of material guiding plates 18 together. The scraping plate 19 is in contact with the inner wall of the box body 1. One end of each of the plurality of fixed tubes 13 is slidably connected with a sliding rod 14. One end of each of the plurality of sliding rods 14 is fixedly connected with an extrusion plate 15. The material guiding plate 18 is located in the moving direction of the extrusion plate 15. A return spring 16 is arranged in each of the plurality of fixed tubes 13. Two ends of the return spring 16 are fixedly connected with the sliding rod 14 and the fixed tube 13 respectively. A fixed cylinder 36 is fixedly connected to the top of the box body 1. A sliding piston 35 is slidably connected to the fixed cylinder 36. A telescopic partition plate 38 is jointly installed at the bottom of the sliding piston 35 and the inner wall of the fixed cylinder 36. An air storage cavity and an air pumping cavity are arranged inside the fixed cylinder 36. The air storage cavity and the air pumping cavity are located on both sides of the telescopic partition plate 38 respectively. A rotating tube 11 is rotatably connected to the bottom of the fixed cylinder 36. The rotating tube 11 is communicated with the air storage cavity. The driving unit includes a motor 3 fixedly connected to the top of the box body 1. The output end of the motor 3 is connected with a driving shaft 31 through a coupling. A bevel gear 312 is fixedly connected to one end of the driving shaft 31 and the rotating tube 11 respectively. The two bevel gears 312 are meshed with each other. A cam 32 is fixedly sleeved on the driving shaft 31. A connecting rod 34 is fixedly connected to the top end of the sliding piston 35. A strip-shaped plate 33 is fixedly connected to the bottom end of the connecting rod 34. The strip-shaped plate 33 is in contact with the cam 32. Through the setting of the scraping and extrusion unit, the motor 3 drives the driving shaft 31 to rotate. The driving shaft 31 rotates to drive the rotating tube 11, the sliding tube 12, and the fixed tube 13 to rotate through the two bevel gears 312. The rotation of the fixed tube 13 drives the brackets 17, the material guiding plates 18, and the scraping plate 19 to rotate. The rotation of the scraping plate 19 can scrape the remaining material adhered to the inner wall of the box body 1, so that the scraped remaining material moves downward and falls on the material guiding plate 18. The driving shaft 31 rotates to drive the cam 32 to rotate. Each time the cam 32 rotates, it drives the strip-shaped plate 33 to move downward. The downward movement of the strip-shaped plate 33 drives the connecting rod 34 and the sliding piston 35 to move downward. The downward movement of the sliding piston 35 squeezes the gas in the air storage cavity into the plurality of fixed tubes 13 through the rotating tube 11 and the sliding tube 12, so as to make the gas push the sliding rod 14 and the extrusion plate 15 to move, so that the extrusion plate 15 contacts the material guiding plate 18. Since the adhered remaining material is easy to agglomerate, the agglomerated remaining material can be broken, thereby improving the mixing effect of the materials.

[0038] Further, a telescopic spring 37 is sleeved on the sliding piston 35. Two ends of the telescopic spring 37 are fixedly connected with the fixed cylinder 36 and the connecting rod 34 respectively. Through the setting of the telescopic spring 37, when the protruding end of the cam 32 is far away from the strip-shaped plate 33, the telescopic spring 37 can drive the sliding piston 35 to reset.

[0039] Further, two fixing plates 2 are fixedly connected to the fixed pipe 13. A rotating shaft 21 is rotatably connected to the two fixing plates 2 together. A V-shaped plate 22 is fixedly sleeved on the rotating shaft 21. One end of the rotating shaft 21 is slidably connected with a sleeve 24. An installation block 23 is fixedly connected to both the sleeve 24 and the extrusion plate 15. An extrusion column 25 is fixedly connected to the inner wall of the sleeve 24. A spiral groove 26 is formed on the rotating shaft 21. The extrusion column 25 is located in the spiral groove 26. Through the arrangement of the V-shaped plate 22, the movement of the extrusion plate 15 drives the movement of the installation block 23, the sleeve 24 and the extrusion column 25. The movement of the extrusion column 25 extrudes the spiral groove 26 to drive the rotation of the rotating shaft 21 and the V-shaped plate 22. The rotation of the V-shaped plate 22 can turn over the material.

[0040] Further, a reciprocating thread groove is formed on the rotating pipe 11. A reciprocating shaft sleeve 4 is adaptively installed on the reciprocating thread groove. A fixing ring 41 is fixedly connected to the bottom of the reciprocating shaft sleeve 4. The fixing ring 41 is rotatably sleeved on the sliding pipe 12. Two limiting rods 42 are fixedly connected to the inner wall of the top of the box body 1. The reciprocating shaft sleeve 4 is slidably sleeved on the two limiting rods 42. Through the arrangement of the reciprocating thread groove, the rotation of the rotating pipe 11 drives the reciprocating movement of the reciprocating shaft sleeve 4 through the spiral groove 26. The reciprocating movement of the reciprocating shaft sleeve 4 drives the movement of the fixing ring 41, the sliding pipe 12 and the fixed pipe 13, so that the material guiding plate 18, the scraping plate 19 and the V-shaped plate 22 move, thereby improving the effects of turning over, scraping and stirring the material.

[0041] Further, the intermittent discharging unit includes a feeding pipe 5 fixedly connected to the box body 1. The top end of the feeding pipe 5 is fixedly communicated with a feeding box 51. The bottom end of the feeding pipe 5 is fixedly communicated with a discharging box 52. A discharging port 53 is fixedly connected to the bottom of the discharging box 52. A baffle 54 is slidably connected to the feeding pipe 5. A fixing block 56 is fixedly connected to the top of the discharging box 52. A movable rod 55 is slidably connected to the fixing block 56. One end of the movable rod 55 is fixedly connected to the baffle 54. The other end of the movable rod 55 is fixedly connected with an inclined rod 57. An extrusion rod 59 is fixedly connected to the reciprocating shaft sleeve 4. The extrusion rod 59 is located directly below the inclined rod 57. A mounting spring 58 is sleeved on the movable rod 55. The two ends of the mounting spring 58 are respectively fixedly connected to the fixing block 56 and the movable rod 55. Through the arrangement of the intermittent discharging unit, the movement of the reciprocating shaft sleeve 4 drives the movement of the extrusion rod 59. When the extrusion rod 59 moves upward and contacts the inclined rod 57, the extrusion rod 59 extrudes the inclined rod 57 to drive the movement of the movable rod 55 and the baffle 54 outward. The movement of the baffle 54 opens the feeding pipe 5, so that the material in the feeding box 51 enters the discharging box 52 through the feeding pipe 5, and then is discharged through the discharging port 53. When the extrusion rod 59 moves downward and away from the inclined rod 57, the mounting spring 58 drives the baffle 54 to reset and closes the feeding pipe 5, thereby enabling intermittent feeding and making the material mix more evenly.

[0042] Further, a one-way air outlet pipe 310 is fixedly connected to the top of the box body 1. The top end of the one-way air outlet pipe 310 is fixedly connected to the bottom of the fixed cylinder 36. A one-way air inlet pipe 39 is fixedly connected to the fixed cylinder 36. Both the one-way air outlet pipe 310 and the one-way air inlet pipe 39 are communicated with the air pumping cavity. The bottom end of the one-way air outlet pipe 310 is fixedly connected to a jet head 311. Through the arrangement of the jet head 311, when the sliding piston 35 moves downward, the gas in the air pumping cavity can be squeezed into the jet head 311 through the one-way air outlet pipe 310 and ejected by the jet head 311. The ejected gas blows the materials falling from the discharge port 53, thereby expanding the range of material falling and making the materials more evenly mixed. When the sliding piston 35 moves downward, air can be introduced through the one-way air inlet pipe 39.

[0043] Further, a discharge pipe 6 is fixedly connected to the bottom of the box body 1. Through the arrangement of the discharge pipe 6, the materials that have completed stirring can be discharged through the discharge pipe 6.

[0044] Specific implementation steps: When in use, put various raw materials to be mixed into the feeding box 51, start the motor 3 to drive the drive shaft 31 to rotate. The rotation of the drive shaft 31 drives the rotating tube 11 to rotate through two bevel gears 312. The rotation of the rotating tube 11 drives the sliding tube 12 and the fixed tube 13 to rotate. The rotation of the fixed tube 13 can stir the materials, so that the materials can be fully mixed. The rotation of the fixed tube 13 drives the bracket 17, the guide plate 18 and the scraper 19 to rotate. The rotation of the scraper 19 can scrape off the remaining materials adhered to the inner wall of the box body 1, so that the scraped remaining materials move downward and fall on the guide plate 18, and move downward on the guide plate 18. The rotation of the drive shaft 31 drives the cam 32 to rotate. Each rotation of the cam 32 drives the strip plate 33 to move downward. The downward movement of the strip plate 33 drives the connecting rod 34 and the sliding piston 35 to move downward. The movement of the sliding piston 35 drives the telescopic spring 37 to compress and undergo elastic deformation. The sliding piston 35 moves downward to squeeze the gas in the air storage cavity into the plurality of fixed tubes 13 through the rotating tube 11 and the sliding tube 12. Then the gas pushes the sliding rod 14 and the extrusion plate 15 to move, so that the extrusion plate 15 contacts the guide plate 18. The movement of the sliding rod 14 drives the return spring 16 to compress and undergo elastic deformation. Since the adhered remaining materials are easy to agglomerate, the agglomerated remaining materials can be broken, thereby improving the mixing effect of the materials. When the protruding end of the cam 32 moves away from the strip plate 33, the telescopic spring 37 drives the sliding piston 35 to reset, and the return spring 16 drives the sliding rod 14 to reset, so that the gas in the fixed tube 13 returns to the air storage cavity. The movement of the extrusion plate 15 drives the mounting block 23, the sleeve 24 and the extrusion column 25 to move. The movement of the extrusion column 25 squeezes the spiral groove 26 to drive the rotating shaft 21 and the V-shaped plate 22 to rotate. The rotation of the V-shaped plate 22 can turn over the materials. The rotation of the rotating tube 11 drives the reciprocating shaft sleeve 4 to move reciprocally through the spiral groove 26. The reciprocating movement of the reciprocating shaft sleeve 4 drives the fixed ring 41, the sliding tube 12 and the fixed tube 13 to move, so that the guide plate 18, the scraper 19 and the V-shaped plate 22 move, thereby improving the effects of turning over, scraping and stirring the materials. The movement of the reciprocating shaft sleeve 4 drives the extrusion rod 59 to move. When the extrusion rod 59 moves upward and contacts the inclined rod 57, the extrusion rod 59 squeezes the inclined rod 57 to drive the movable rod 55 and the baffle 54 to move outward. The movement of the movable rod 55 drives the mounting spring 58 to stretch and undergo elastic deformation. The movement of the baffle 54 opens the feed pipe 5, so that the materials in the feeding box 51 enter the discharging box 52 through the feed pipe 5, and then are discharged from the discharging port 53. When the extrusion rod 59 moves downward and away from the inclined rod 57, the mounting spring 58 drives the baffle 54 to reset and closes the feed pipe 5, so that intermittent feeding can be carried out, making the materials mix more evenly. When the sliding piston 35 moves downward, the gas in the air injection cavity can be squeezed into the jet head 311 through the one-way air outlet pipe 310 and sprayed out by the jet head 311. The sprayed gas blows the materials falling from the discharging port 53, thereby expanding the falling range of the materials.The material is made to mix more evenly. When the sliding piston 35 moves downward, air can be introduced through the one-way intake pipe 39.
